REFRIGERATOR.

ApplicationV filed .Tune 22, 1922. `Serial No. 570,151.

To all iii/tom t may concern."

Be it known that I, TILLIAM Soo'rrr lMoria'- GoirnnY, a resident of the town of Dalhousie,

in the Province of New Brunswick and Dominion of Canada, have invented certain' new au d useful. Improvements in Refrigerators, of which the following is a specification.

This invention relates to improvements in refrigerators and the like, andthe objects of the invention are to provide simple, economical and effective meansA for utilizing the frost made from melting ice in a refrigerator before it runs off as waste.

My improved refrigerator, therefore, may be more particularly described as a combination ice, salt and self-circulating brine rei'rigerator.` As heretofore constructed, refrigerators and especially house refrigerators were losing all the frost made from melting ice through the. waste pipes while with my improved construction, this waste having been converted into' brine by the addition of salt is circulatedaround the storage compartments of a refrigerator before being finally discharged. In this manner, I utilize at leastseventy-five per cent. of the frost from melting ice that was formerly wasted and run off directly in the water. The saving in ice and the maximum of freezing efficiency thus obtained' with my device can be easily understood and appreciated.

Further objects are to` provide` means of this character, in which the various parts will be enabled to better perform the functions required of them.

Vith the foregoing and other objects in view, the invention consists essentially in the combination and arrangement of parts as hereinafter described in the specification and illustrated in the accompanying drawings.

In the drawings:

Figure 1 is an enlarged perspective view of a refrigerator.

Figure 2 is a vertical section.

Figure 3 is a section on the line 3-3, Figure 2.

In the drawings, like characters of reference indicate corresponding parts in each figure. y

Referring tof the drawings:

A designates a refrigerator of any wellknown construction, and here as an example shown as a house refrigerator of the double kind. My invention, however, is equally applicable to all sizes and makes of refrigerators, refrigerator-ships or otherwise. In the example here shown of a house refrigerator and designated by the letter 131 as already mentioned, B, C, D, E, and F are storage eon'ipartinents and 10 is the ice compartment, all lined or provided with, preferably, zinc walls or the like, the compartment 10 being preferably tapered towards the bottom so that the ice with whicl'i when broken, I mix salt to form the brine and prevent it from freezing, will' settle, gradually from the top, allowing the cold" to' descend through-the several compartments.

11 is a sharp freezer or freezing chamber comprising' a casing member' preferably made of zinc and designed so to fit into, the bottom of the icek compartment as to leave on each side, spaces or passageways connect ing the ice compartment with the brine chambers. which are formed between the walls, top and bottom of the storage compartments. By this means the liquid converted into brine by the addition of salt and flowing from the ice compartment will bel diverted to; the passageways on eachA side of the 'freezing member or sharp freezer and4 thence directly to the brine chambers, whereby thel air in the freezing chamber will beV maintained at a substantially lower temperature than the other compartments. 12'-, 13'-, `14 and 15, arebiine chambers formedk in the galvanined metal walls of theA several com partments on each-side and bottom` andcontiniied around the i bottom and upY the outer sides to form the chambers 16 and 17 and across the top to form the chambers 18 and 19, thus completely surrounding the several compartments C' and D. These brine chambers are really hollow walls which provide means of circulation for the waste ice water converted into brine and then charged with frost, which is essentially a feature of my invention, as this brine in its circulation around the several refrigerator compartments maintains the temperature therein at freezing point or below, while being brine it does not freeze itself.

Further` it will be noted that the circulation starts with the melting ice, then, as

of the compartments where, as' hereinafter more fully described, it is tapped by overow pipes, thus the circulation is complete and continuous.

In a position in the brine chambers which will ensure that they are full of brine circulating around and across the top of the storage compartments of the refrigerator, Iv

provide orifices 20 to which are connected the overflow pipes 2l. rlhese overflow pipes are preferably mounted on a level slightly above the bottom of the sharp freezer and the brine tank, so that it will be impossible for any warm outside air to enter the brine chambers.

22 are air vent pipes extending from adjacent to the orifices or apertures 20 to outside refrigerator, and open at the top, designed to prevent the overflow from syphoning brine. 222L is a valve for draining the brine tank when required. -One of the overflow pipes 2l may be turned up at the end, When all the circulation of brine will go to the opposite side, making one side cooler than the other. This can be arranged in very large refrigerators with a valve.

23 is the top of the refrigerator fitted and secured with felt gasket and screws, so that it can be taken off when the two overiiow pipes are unscrewed, when the freezer and brine chambers will all lift out to be thoroughly cleaned when necessary.

4rom the foregoing, it will be seen that my improved method and construction provides for refrigerators of all kinds, a perfect circulation of frost supplying brine from the ice water that heretofore was discharged as waste, the simplicity of the principle involving the hollow walls for the different storage compartments connecting with the sharp freezer or brine tank in such manner as to ensure, in combination with the placing of overflow pipes, a perfect circulation of the brine in every direction within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification. and drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is:

A refrigerator comprising in combination an ice compartment, storage compartments along side and below the ice compartment, a freezing chamber comprising a hollow casing member adapted to form a bottom for the ice compartment leaving passageways on each side, whereby the flow of liquid from the ice compartment is divided, brine circulating chambers communicating with said passageways and extending downwardly around and across the top of the lower storage compartments, whereby the brine from the ice compartment is circulated, first downwardly and then around and across the top of the storage compartments, brine discharge means communicating with the uppermost portions of said brine chambers, whereby a continuous circulation of the brine is maintained.

ln witness whereof I have hereunto set my hand in the presence of two witnesses.
